IMPROVEMENT IN ALARM ATTACHMENTS FOR MEASURING-CANS.

Specification forming part of Letters Patent No. 151,32, dated May26,1874; application filed January 17, 1874.

To all whom t may concern Be it known that I, EDWARD A. TEMPLE, ofChariton, in the county of Lucas and State of Iowa, have invented a newand useful Improvement in Alarm Attachment for Automaticl\Ieasuring-Ga-n, of which the following is a specification:

Figure 1 is a side View of the operating mechanism of an automaticmeasuring device, to which an alarm has been applied. Fig. 2

is a front view of the same, part being broken,

away to show the construction.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved alarm attachmentfor the automatic measuring-can described in Letters Patent No. 119,114,issued to C. M. Bridges, September 19, 1871, to give notice when thedesired amount of liquid has been (hawn from the can.

The invention will rst be fully described, and then pointed out in theclaim.

G is the pulley or wheel aroundwhich the float and weight cord passes. Lis a stationary disk, attached to the frame in which the spindle ot' thepulley G revolves. J is the ratchet or notched disk, upon which thescale or division marks are made, and which runs loosely upon thespindle of the pulley G, where it is secured in place by a nut, M. N isa spring placed upon the spindle of the pulley G, the inner end of whichrests against a pin or other stop attached to said spindle, and itsouter end rests against the disk J with suicient force to enable thesaid spindle to carry the said disk with itin its forward movement, butwill allow the said disk to stand still while the pulley G is turnedbackward by the rise of the float-tube.Y The tension of the spring N isadjusted by adjusting the nut M, between which and the said spring N theratchet-disk J is clamped. The parts thus far described are the same asthose described in Patent No. 119,114. K is a pawl, which passes througha slot in the stationary disk L, and rests upon the edge of theratchet-disk J, so as to drop into the notches of said'disk when alneasure has been drawn out. The end of the pawl K is provided with anindexnger, pointing to the division-marks of said disk J. The pawl K,after passing through the disk L, is bent at right angles, and isattached to a short rock-shaft, Q, that works in a bracket attached tothe disk L. The pawl K is held down upon the edge of the ratchetdisk Jby a spring, It, one end otl which is connected with the said pawl K,and its other end is connected with the stationary disk L. To therock-shaft Q is attached the end of the bell-hammer S, so that each timethe pawl K drops into a notch of the ratchet-disk J, the hammer S maystrike the bell T, and give notice that one measure has .iiowed from theneat-tube of the can.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination, with hammer S and bell T, of theslotted disk L and scale-ratchet l), bent pawl and index K, shaft Q, andspring R, as described, substantially as and for the purposes set forth.
